Kaley Cuoco has officially called it quits on her marriage to Ryan Sweeting. The Big Bang Theory actress cited irreconcilable differences in divorce documents obtained by Us Weekly on Monday, Sept. 28.

According to the filing, the couple’s date of separation is listed as Sept. 3. Cuoco, 29, and Sweeting, 28, who were only married for 21 months, had a prenuptial agreement. Both spousal support and property assets, according to the documents, were agreed upon in their prenup, one month before they said “I do” on Dec. 31, 2013.

Cuoco, who had taken her husband’s last name, is also requesting her name be restored to Kaley Christine Cuoco.

"Kaley Cuoco and Ryan Sweeting have mutually decided to end their marriage," her rep previously told Us in a statement on Friday, Sept. 25. "They ask for privacy at this time. No further statement will be issued regarding this matter."

Prior to announcing their split, the highest paid TV actress hinted at their breakup by deleting nearly all photos of Sweeting from her Instagram account.
